FALL-BOARD FOR UPRIGHT PIANOS.

SPECIFICATION forming part of Letters Patent No. 247,473, datedSeptember 27, 1881 Application filed July 28, 1880. (No model.)

To all whom it may concern:

Be it known that I, GHARLEs E. BOURNE, of Boston, Massachusetts, haveinvented an Improvement in Fall-Boards for Upright Pianos, of which thefollowing is a specification.

The object of my invention is to so construct the fall-board of anupright piano that it maybe thrown back in opening the instrumentwithout interfering with the music-rack, and also to so connect it withthe music-rack that the latter will be put in position automatically bythe opening of the instrument.

In the accompanying drawings, Figure 1 is a side View of an uprightpiano containing my invention, showing the position of the parts whenclosed. Fig. 2 is a similar view of the instrument on a larger scale,showing the position of the parts when open, the dottedlinesalsodndicatin g their position when closed. Fig. 3 shows one of the armsto which thefront portion of the fall-board is attached. Fig. 4 is afront view of the instrument, showing the position of one of these armsat the side of the fall-board.

The fall-board is made in two parts, A and B, united by hinges openingupward. The front portion, A, is attached to the case of the piano bytwo arms, (3 0, one on each side, fastened rigidly at the upper ends tothe sides of the tall-board, and pivoted by means of open slots at thelower ends to studs or pins in the case of the instrument. The rear endof the part B is also attached to the case above it by when thefall-board is thrown back in opening the instrument.

Behind and above the fall-board, and pivoted to the case of theinstrument,is the curved lever E, whose lower end is in contact with the40 back side of the fall-board B, while the upper end rests against theback side of the musicrack F, which is suspended by hinges at its upperedge in the usual manner.

Attached to the musicrack is a spring, G, 5 the other end of whichisfastened to thepianocase, so as to aid in bringing the music-rack backto a perpendicular position when the pressure of the lever E iswithdrawn.

The construction and arrangement of the parts are such that when thefall-board A is raised and thrown back in opening the instrument thepart B is carried backward and downward within the case, allowing thepart A to be turned up under the music-rack without interfering with it.At the same time the pressure of the partB upon thelever E throws thelower end of the music-rack outward into place.

WVhat I claim, and desire to secure by Letters Patent, is

1. The jointed fall-board A B, suspendedby the arms 0 O D D,substantially as and for the purpose described.

2. The fall-board A B, lever E, and musicrack F, combined and arrangedsubstantially as and for the purpose described.
